DISCLAIMER: Lenses from Japan and Korea are not US-FDA approved, usually non-prescription, and usually only available in standard measurements 8.6 B.C., 14mm diameter which may not be your size! Notable brands are FDA approved in the country of origin (Korean FDA, Japanese FDA). If you're new to contacts, stick to what's readily available and never get contacts without getting an eye exam first!

Fixed

The US-FDA would rather control and give its stamp of approval to brands manufactured within the country and select Western European nations. Honestly if you're looking at an Asian brand of lenses and are unsure about them, it'd be wise/easy/safe to contact the eye doctor's office and get a professional opinion on that particular brand. I'll see if I can dig up a list of Korean and Japanese FDA approved lenses for reference.
